Hi all! Here is a breakout board I put together in the shape of a thumb keyboard for the Teensy 3.2.



Beginner friendly through hole soldering.
60 keys arranged in a familiar qwerty layout with number keys arranged in a numpad.
SPI, I2C, and 2 additional GPIOs broken out. Aside from these pins all others are used to read the key matrix.
Teensy can be rotated with the micro USB facing up or down. Breakout pins will only work as expected with USB facing up.

I'm still waiting on a rev v1.1 board and will update when that arrives. Code is working but it needs some cleanup before I can share.
